type.

E. PETERS,

The invention has among its various objects the provision of an arrangement whereby the sack or ink container may be easily compressed to deiiate it, the initial operation of the compressing means acting upon the closed end of the sack first, thereby exany sediment which may have become odged in the sack at said end during the time it is carried in the pocket of the user.

It is also an object of the invention to a5 provide an arrangement .whereby the sack may be partially epressed or expanded and held in this condition. Thus the attention of the user may be momentarily distracted during the filling operation without necessitating the complete compression of the sack and also the expulsion of the writing` fluid previously taken into the sack to complete the filling operation. l It is a. further object to produce a device capable of performing these results the construction of which cannot at any time be accidentally operated.

The invention has as an additional object the production of a construction for accomd0 plishing these advantages which is convenlently arranged with relation to the barrel of. the pen and also arranged so that the ornamentation of the barrel will not be interfered with. It is also an object to' provide a simple and inexpensive arrangement of this nature which can readily be assembled for use and disassembled for re 'rs and in which the parts will be held 1n their proper relative position within the barrel to permit the insertion of the sack within the barrel, and also to provide a means for limiting the movement lof that portion which is actuated Founto cause the sack to be compressed or expanded.

The invention has these and other objects all of which will be explained in detail and more readily understood when read in conjunction with the accompanying drawings, in which one embodiment of the invention lis illustrated, and in which-- Fig. 1 is a longitudinal section of a fountain pen having the invention applied thereto and showing the position of the parts when the sack is expanded or filled with writing fluid;

Fig. 2 is a sectional view similar to Fig. 1 showin the relative position of the parts while t e sack isbein compressed;

Fi 3 is a view siml ar to Figs. 1 and 2 showing the sack fully compressed; and

Fig. 4 is a sectional plan View of the parts shown in Figs. 1, 2 and 3.

In the structure shown in the drawings the use of the outer barrel 10 is contemplated this being open at both ends for the reception of the ink container or sack 11, and the sack actuating mechanism generally designated by the numeral 12, it being understood tllat one end of the sack is connected with t e that this portion 13 closes this end of the barrel, also that thev fluid enters the sack through this portion 13 in the usual manner.

The opposite end of the barrel 10 is provided with the internal screw threads 16 into which is threaded the end 17 of the portion 18 Awhich is rotatable relatively to the barrel and relatively to the remaining mechanism and provides the means for controlling said mechanism and the consequent compression or expansion of the sack 10 during the filling operation. These threads |16 and 17 are preferably a left hand thread and of a pitch which will cause the rapid operation of the mechanism within the barrel, yet will not permit of an accidental operation. A headed member'19 projects from the member 18 and is loosely seated in the member 20, and connects this member 20 and the member 19 together, these parts being held against relative longitudinal movement by the pin 21 which is carried by the'member 20 andconfines the head between the wall of the member 20 and the pin 21. I desire to have portion 13 which carries the pen 15 and it understood that the precise arrangement or connection between the partsv 18 and 20 as shown, need not be adhered to, as any other arrangement whereby relative rotatable movement of the parts 18 and 20 is permitted. This member 2() is confined 1n th barrel 10 and moves longitudinally with relation to the barrel withthe member 18 when said last mentioned member is operated. This member 20 is preferably tubular and has a portion ofthev wall cut away to provide the slot 28 and is also rovided with a pin 22 arranged transverse y to the axis lof the member 20. This slot 28 and pin 22 cooperate with the end 23 ofthe lever 24 to operate it. This lever is pivoted at 25, the opposite end thereof being pivotally connected at 27 with the bar 26 which rests upon the sack 11. The end 23 of the lever 24 is arranged in the slot 28 and between the pin 22 and the wall of the member 20, and is formed to produce a cam which cooperates with the pin 22 and the wall to causel operation of the bar 26 to compress or release the sack when the member 18 is operated. The cam shaped portion of the lever has a hooked end portion which engages the pin 22 to thereby limit the movement of the member 18 when same is moved outwardly, the inward movement of this member 18 being limited by the shoulder 29, contacting with the end of the barrel 10. The lever 2d is provided with the transverse portions 30-30, which are bent to conform wlth the shape of the interior of the barrel and are provided with apertures for the reception of the pin 31 upon which said lever is pivoted This arrangement produces a structure which securely yet freely holds the lever 1n its proper relative position within the barrel and prevents any sidewise movement thereof.

From the foregoing explanation of the structure it can readily be seen that upon the rotation of the member 18 in one direction the same will be caused to move outwardly with relation to the barrel of the pen. This movement will cause the member 20 to be moved therewith. By virtue of the fact that the pin 22 is in engagement with the under surface of the cam end of the lever 24: this last mentioned end will be raised and the opposite end thereof lowered upon the outward movement of the member 18. This depresses the bar 26 and compresses the sack 11. It is also evident that when the member 18 is moved in the opposite direction the face of the member 20 adjacent the slot 28 will engage the upper surface of the cam and cause the end of the lever 24 to which the bar 26 is connected to be raised permitting the sack to expand, which draws the Huid into it and fills the same. By pivoting` the bar 26 to the lever 24 between its ends, and allowing the. bar to be greater in length from the pivot to the forward end, the bar intacta will assume the position shown in Fig. 2 wherein the closed end of the sack is shown as'being depressed to a greaterextent than the opposite-end. This causes the sediment contained at this end to be forced vout of the sack.

Tt is also evident that by employing an ar. rangement such as the threads 16 and 17 that the member 18 may be moved to intermediate positions, and that the mechanism controlle thereby will be held in said intermediate positions depending lupon the particular position of the member 18. Thus the filling operation may be momentarily suspended` and resumed later without neces'- sita-ting the expulsion of the duid previl ously taken into the sack, as required by various structures now on the market.

It is also evident by the arrangement shown that the accidental operation of the mechanism is eliminated, this being prevented by utilizing an actuating device that is rotatable and which may be moved to any intermediate position and held against movement while in said intermediate position.

llt is further evident that the actuating means is positioned so that the pen may be conveniently and easily filled and that said actuating` means i-s arranged so that the barrel of the pen may be ornamented without interference by said actuating means.

Having described one embodiment of the invention it is obvious' that changes and modifications may be resorted to without departing from the spirit of the appended claims.
